JOHN NEWMN, F NEW Y0 it it DOUBLE-ROW BALL-BEARING.

To all whom it may concern;

Be it known that l, JOHN NEWMANN, a

. citizen of the United States, residing -in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Double- Row Ball-Bearings, of which the following is a specification.

The present invention relates to ball bearings having two or more rows or sets of balls.-

Oneobject of my invention is to provide a construction which without the necessity of filling openings and without any cages will allow the use of a greater number of balls than in the usual one row ball bear- 'ing of equal dimensions and which will at the same time reduce the width of the ball bearing to a great, extent.

A further object of my invention is to provide a separator which will not only separate two neighboring balls of one row, but

also hold a ball of the adjacent row in staggered or intermediate relation to the balls of the other row.

With these and other objects in view my invention consists in the construction, combination and arrangement of parts as will be hereinafter fullv described and set forth in the appended claims.

-Reference is had to the accompanying drawing which forms part of this specification andin which similar numerals denote bushing 6.

' corresponding parts in the several figures,

Figure 1 bemg a vertical section of my new bearing; Fig. 2 showingthe construction and position of my separators relative to a doub e row of balls; and Fig. 3 a sectionalview of an adjustable end separator.

The double row ball bearing comprises an outer shell or rin and an inner cone composed of two annu ar sections 5, 5". The outer shell is formed on its inner periphery with annular grooves of circular cross section which are arranged close to one another so that their centers are separated by about the diameter of a ball. The sections 5 and 5 of the inner cone are annular members each formed with an outer annular flange 5 and a race or track 5 These two sections can be joined to each other bymeans of a. bushin 6 after the parts are completely assem led.

The balls 3, 3 are arranged in two rows which are staggered relative to one another Specification of Letters latent.

and those of each row are separated from one another. The two rows of balls are held in staggered relation by separators 1 of whlch each consists of a substantially "Ti -shaped member, the branches of which are iormed at their ends with bowl-shaped pockets 4- 4: and 4?. Two oppositely located bowls as l and 4 are adapted to engage parts of two neighboring balls of a row, while the bowl 4: on the laterally projecting branch or arm serves to engage a First, one row of balls is assembled in 7 one of the races of the outer ring while the sections of the inner ring are removed, by lntroducing'alternately the 'balls and spacers 4 then looking them together by the adjustable spacer 7. Then the balls of the second row are-introduced to rest in the bowls 4 of the members 4, which balls are then looked in position by the last adjustable member 7. Finally the two sections of the inner cone are inserted and joined by the Since by the employment of my new spacers 4; the two 'rows of balls will be held in proper alinement relative to one another the provision of separate grooves in the outer ring can be dispensed with, and instead a groove of the shape similar to 5 provided therein.

It will also be clear that my new spacer is not limited to double row bearings but can be equally applied to bearings with three or more rows of balls.

Since the construction ma be variously modified without departing rom the spirit of my invention, 1 do not wish to restrict myself to the details described and shown.

What I claim anddesire to secure by Letters Patent is:

1. A ball bearing comprisin two rings having ball-races, sets of balls etween said rings and separators of which each is adapted [0 embrace parts of two neighboring balls set, so that the balls of the latter set are in a staggered relation to those of the other set. 2. A ball bearing comprising two rings having ball-races, sets of balls between said rings and separators each formed with pockets at its ends and a lateral pocket to engage parts of. two neighboring balls of one set and part of a ball of an adjoining set so that the balls of the latter set are in a staggered relation to those of the other set.

3. A ball bearing consisting of two rings having ball races adjoining one another, the inner ring being composed of two annular halves, two rows of balls between said rings and separators each adapted to engage parts of two neighboring balls in one row and part of a ball in the adjoining row so that the balls in the latter row are in a staggered relation .to those of the first row.

4. In a ball bearing having two rows of balls, a T-shaped separator formed at the free end of each arm with bowl shaped pockets.

In testimony whereof, I aflix my signature 25 in presence of two Witnesses.

JOHN NEWMANN.
